My coworker told me everyone at work warned him about me… and it messed with my head

I’m a pretty quiet person at work.

I usually keep to myself, do my job, and go home. I’m not very social, but I’m not rude either. I’ve always assumed people just saw me as the quiet type.

Recently a new coworker joined our team. After working together for a few days he said something that honestly caught me off guard.

He told me that before he started, several people warned him about me.

They told him that I’m difficult, that I’m rude, and that people don’t like working with me.

The strange part is that he said he was surprised because he actually found me easy to work with.

But hearing that people talk about me like that behind my back really got into my head.

Now I keep replaying it and wondering if I somehow give off the wrong impression without realizing it.

Has anyone else dealt with something like this at work?

How do you handle knowing people might have a completely different perception of you than who you actually are?
